  That's good. For my (HP) laptop, 'powercfg /batteryreport' is 'lying'
about the 'DESIGN CAPACITY', taking the 'FULL CHARGE CAPACITY' as the
'DESIGN CAPACITY'. So good that it's telling the truth for you. That
only shows that not all laptops are made equal! :-)

  No, calibrating the battery doesn't harm the battery. On the contrary,
certain problems - like unexpectedly low capacity, charged percentage
not matching reality (I had that this summer), etc. - can sometimes be
fixed by calibrating. So if the information source is/sounds credible,
you can follow that advice.

  As for there being any point recalibrating the battery, considering
your usage: Probably not, but it can't hurt and it's not that much
effort. But *if* you do it, do it right, i.e. follow the procedure fully
and a few times, don't cut corners, because that won't help.
